Right before the end, I had a DEC EISA 486DX50 with 64MB's, an Adaptec 1740, and a DEC RZ25, and after playing with all the tuning parameters I could find, I think I ended up with 1.8MB/s reading 1.4MB/s writing I think it would've been significantly better with DEC's RZ26, which is a better drive. Also, the 1740 is kind of old, all things considered. I understand Adaptec is bringing out the 2700 series controllers, and I would be very interested in the performance of those. -- Jaye Mathisen, COE Systems Manager (406) 994-4780 410 Roberts Hall,Dept. of Computer Science Montana State University,Bozeman MT 59717 osyjm@cs.montana.edu
